Nitrogen Generating Systems
I just flew a new Boeing 737 with a Nitrogen Generating System that displaces fuel tank vapor with inert nitrogen gas. This new aircraft has the System placarded inop. I'm looking for any info on the system and when the FAA or ICAO might mandate it's operation? Is the system cost extra to come from boeing operating (like an option) that the company has not paid for? The aircraft was put into operation the 8-23-07, nice new plane smell and no fingerprints on the glass...nice!
